Abstract: The invention concerns a food composition, suitable for shallow frying, comprising triglycerides, wherein least 60 wt. % of triglycerides is of vegetable origin, and 0.05-3 wt. % sunflower lecithin. The invention further concerns a process for the preparation of hydrolyzed sunflower lecithin.

Abstract: Oils, extracted from vegetables and animal tissues contain impurities such as waxes that can be removed in a refining process, including dewaxing of the oils that include removal of oils by filtration through membranes. During filtration, the impurities stick to the membranes, which causes a reduction in flux through the membranes. The initial top flux can be approached again by regularly cleaning the membranes including steps of: backblowing with gas, backflushing with edible oil, and treating the membranes with alkaline material. The cleaning method is particularly suitable for cleaning membranes in the form of microfilters having an average pore diameter of 0.5-5 &mgr;m, which are used in the refining process.

Abstract: The present invention relates to a process for the preparation of degummed glyceride oils, which comprises applying an acid degumming treatment to a crude glyceride oil which has not substantially been exposed to enzymatic activity. Preferably such crude glyceride oil has been obtained by heating and pressing glyceride oil containing vegetable material, optionally preceded by a cold pressing step, where the heating comprises an exposure of the vegetable material to a temperature of 30.degree.-80.degree. C. for 0.1-20 minutes, preferably for 0.1-15 minutes, more preferably 0.1-5 minutes, and then to a temperature of 80.degree.-140.degree. C., preferably 90.degree.-110.degree. C. for 1-60 minutes, preferably 15-20 minutes. Residual phosphorus levels of <7 ppm and even <2 ppm can be easily and consistently attained.

Abstract: Triglyceride oils are degummed according to a two-stage process, in which in the first step a substantially concentrated solution of an acid or an anhydride, having a pH of at least 0.5 as measured at 20.degree. C in a one molar aqueous solution, is dispersed in the oil, and in a second step 0.2 to 5 wt.% of water is dispersed in the mixture obtained and an aqueous sludge is separated from the oil after the water has been in contact with the oil-acid-mixture for at least 5 minutes at a temperature below 40.degree. C.
